Preparations for OpIsrael

Many articles and reports have been written regarding the immanent threat of AnonGhost on Israel. The attack, which have already started, should peak at the 7th of April 2013. We have decided to take a more pragmatic approach and prepare our servers. Obviously, we are running Linux and using IPTables as our protection. So, here you have it, our little script to help you avoid and block at least some attempts of DDoS and a bit more.

Please note, this will REMOVE your old rules and logs! Go over the script carefully and adjust it to your purposes. You need to open specific services, add some IP ranges, or any thing else. Please notice the comments. They are for you. Also, there are a couple of traps along the way. You can also download the script using ‘wget http://hackingdefined.org/tools/opisrael_vac.sh‘.

Update

Thanks to Doudou Broda, Bar Hofesh and Tzakhi Malka a few new things have been added. The script will now backup your current IPTABLES rules so that you can restore them later on. A few new modifications have been added to try and block further more attacks.
